MEANS FOR PRUDUCING COPIED EFFECTS ON'WRITTEN 0R PRINTED MATTER.

SPECIFICATION forming part of Letters Patent No. 548,734, dated October 29, 1895.

Application filed December 13, 1894. Serial No. 531,626. (No model.)

To all whom it may concern:

Be it known that LOHAELES ELLsWoRTH ADAMSON, a citizen of the United States, residing at Muncie, inthe county of Delaware and State of Indiana, have invented certain new and useful Improvements in Machines for Producing a Copied Eect on Written or Printed Matter;` and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a new and useful improvement in machines for producing a copied effect on written or printed matter; and the objects of my improvements 4are to construct a machine that will moisten the paper and then dry it at one continuous operation by first passing the paper into the machine between moistened rollers, then carrying the moist sheets around a heated dryingdrum, so that the paper willbe delivered from the machine perfectly dry.

A further object of my invention is to produce the copied effect on the printed matter by passing the sheets with their printed" sur-v faces down in direct contact with one or more cloth-covered rollers, the lower portion ofthe said rollers extending down into the water, which is kept in a pan arranged below the said rollers.

I obtain these objects by the construction illustrated in the accompanying drawings, wherein like letters and igures of reference indicate corresponding parts in the several views, and in which- Figure l is a perspective View of my complete machine. Fig. 2 is a longitudinal vertical section taken on the line a: x of Fig. l. Fig. 3 is an enlarged sectional view of the mechanism for producing the copied effect. Fig. 4 is a longitudinal section of one end of the impression-roller. Fig. 5 is a longitudinal section of one end of one of the copyingrollers. Fig. 6 is a detail perspective view of one end of the water-pan and the two copying-rollers, Fig. 7 is a detail view of the supporting-block; and Fig. 8 is a detail perspective, partly in section, of the delivery side of the copying mechanism.

In constructing my machineI makeaframe consisting of four corner-posts A, two upper side bars A', and two lower side bars A and To'the underside of each upper side barand at the front end of the machine is secured a supporting-block B, each block being held in position by a bolt B', passing through a vertical aperture in the block and secured to the upper side bars.

C represents the copying-rollers, which are placed transversely on the supporting-frame. These rollers are provided with the journals C at their opposite ends and are free to revolve by having their journals C passing through transverse apertures in the block B. One of the journals of the rear roller is provided with an extension G', which extends out beyond the block B, for a purpose hereinafter described.

I use two rollers and secure them parallel withl each other and about one inch apart, as most clearly shown in Figs. 2, 3, and 6. These rollers are preferably made of Wood and are each covered with a soit cloth, such as felt or flannel. Such material I find will retain but little, if any, of the ink-stains when in use.

Below the copying-rollers is supported the Vwater-pan B, which is held in position by the hooks D, which are secured to the pan and to the side bars A. VVThis pan is made somewhat wider than the length of the copyingrollers, so that the rollers may be placed and revolve within the pan. The said pan is kept full of water and the lower portions of the rollers are submerged therein, the upper portions being above the water-level, for a purpose hereinafter described. The pan is also provided with an overflow-spout and a faucet for emptying the Water when desired.

y E represents the feed-table, which is secured to the front portionof theframe and on whichd the printed sheets are placed before being fed into the machine. A feed-belt E is arranged to move between the table E and the front copying-roller C, asshown in Figs. 1, 2, and 3. The belt E passes around two rollers, one of which E is located at the lower IOO edge of the feed-table and the other one E is located in the main frame near the copyingroller.

H represents the impression-roller, which rests on and is supported directly by the copying-rollers C. This roller is kept in its place on 'the rollers C, and is prevented from having a longitudinal movement on the frame by placing the rollers O a short distance apart, so that the periphery of the roller H will rest between the rollers Gand on the adjacent sides thereof, as plainly shown in the drawings. The roller H is shorter than the width of the frame and will rest between the crossbars and be thereby prevented from any trans- Verse movement. The impression-roller is closed at each end, as shown in Fig. 4, and is provided with the studs H', which extend out beyond the cross-bars for convenience in lifting the roller from the frame when desired. |This roller, as before described, rests directly on the rollers C, and is preferably made of a hollow iron pipe, and is sufficiently heavy to exert considerable pressure on the rollers lC and an even pressure on the sheets which pass between them, and it is covered with a soft cloth, such as velvet or flannel. Around this roller are placed threads I, preferably vof silk, which pass around a small roller l, which is journaled in the frame in the rear of the copying-rollers. These threads are placed a suitable distance apart and prevent the printed sheets from sticking to the impression-roller. Similar threads J are placed around the two lower rollers and around a small roller 2, which is journaled in the frame in the rear of the copying-rollers, preventing the sheets from sticking to the said rollers and guiding the sheets out upon the dryingbelt K, all as indicated by the dotted arrows in Fig. 3.

The hollow drying-drum K is located back of the copying-eliect mechanism vand isjournaled on a hollow shaft K', which is supported on the inclined bars A. The said shaft is provided with a series of apertures K within the drum and a gas-pipe and stopcock on one end of the pipe outside of the bar A, as shown in Fig. l. Gas is admitted into the pipe, as desired, burning from the small apertures and heating the drum to dry the sheets when the machine is in operation.

J and L represent the drying-belts,which are made of some firm material which will not be injured by heat, and they may be solid cloth or strips of tape or threads, as desired, as they simply carry the sheets against and around the drying-drum. These belts are arranged on the rollers and drum as follows: The inner belt L passes around and directly against the drum K, passing up and partly around the roller 3, which is journaled on the frame, then over and around the roller 4, which is also journaled on the frame, then down to and around the drum. The outer or long belt J passes over the roller 5, where the Wet sheets drop upon it, then down over the ,Fll' drum, the sheets are then fed one by one with roller 6, thenl against the belt L, around the drum, coming up on top between the rollers 3 and 4, at which point the dry sheet is delivered over on the delivery-board M, which is placed on top of the machine. The belt J is then carried onto the rear of the machine,

where it passes over the roller 7, then down around the roller 8, then forward to the roller 9, then up to the roller 5. These rollers 5, 6, '7, 8, and 9 are supported on and journaled in the frame.

Motion is imparted to the various belts and rollers by placing a sprocket-wheel F and a driving-pulley F on the extension G of the journal of the rear copying-roller C. A sprocket-wheel F is secured to one end of the roller 3 and a similar sprocket-wheel F is secured on the end of the roller E, and around these sprocket-wheels F, F', and F a sprocket-chain G is passed. it will readily be seen that when motion is imparted. to the extension G by means of the drivepulley F the rollers C and H will revolve and that by means of the sprocket-chain and wheels mo- `tion will be imparted to the various belts and rollers, as indicated by the arrows in Figs. 2 and 3.

y The operation of my machine is as follows: `The letters, circulars, or other matter are printed in the ordinary way in a copying-ink, and after they have come from the printingpress they are laid on the feed-table E, and

vthen the copying-machine is started by a driving-belt (not shown) working on the pulley The gas is turned on and lighted in the the printed side down onto the belt E', and the sheets are carried over the two copyingrollers C and under the impression-roller H, out over the rollers 5 and 6 onto the belt J, and around the drum between the belts J and L and delivered on top 4the delivery-board M from between the belts J and L at the point where the two belts separate.

It will be seen that when the copying-rollers C revolve they will impart a certain degree of moisture to the impression-roller H. In passing overthe copying-rollers and under the impression-roller the printed matter is subjected to dampness on each side, which produces a slight tinge or copied effect on the printing. Aslight stain from the ink is washed into the water in the pan, and this water is changed when it becomes too heavily colored. The copying-rollers and impressionroller are covered with a soft cloth-such as felt, velvet, or annel-which I have discovered will not odset or reprint any color or stain on the sheets, absorbing but little if any amount of ink therefrom and giving them the copied effect.

Any ink-stains which remain in the copying-rollers will be washed out as the rollers revolve through the pan of water and the rollers will become saturated with the water from the pan. The impression-roller being heavy and resting directly on the copying- IOL.

IIO

' rollers will, by its weight, press nearly all of the water out of the copying-rollers, and very little if any of the water is transferred to the impression-roller. This surplus water will be forced out of the copying-rollers just in advance of the point of contact of the copying and pressure rollers and the printed sheets will pass directly through this pressed-out water and become thoroughly saturated and will then passbetween the rollers where the water will be pressed out of the printed sheets. This operation is repeated when the printed sheets pass between the second copying-roller and impression-roller. It will be seen by this construction that immediately after the printed sheets have been saturated with water and pressed they are passed around the drying-drum and dried. This I regard as an important feature of my invention, for the reason that unless the sheets were at once dried the wet ink would soak through the paper, thereby making the copied effect imperfect and one easily distinguished from an original type-written letter.

I am aware that many minor changes can be made in the construction and arrangement of parts without in the least departing from the nature and principle of my invention.

Having thus described my invention,what

I claim as new, and desire to secure by Letters Patent., is-

1. In a machine for producing a copied effect on written or printed matter, the combination with a supporting frame, of a dampened copying roller on the frame for produc ing a copied effect, means for dampening the copying roller, a drier on the frame, means for exerting pressure on the copying roller, and means for passing the printedsheets between the copying roller and pressure mechanism and through the drier, while the sheets are damp and after having been passed through the said dampening and pressure mechanisms, substantially as described.
